Manuscript Summary: This manuscript of Six âges du monde, created in France at the end of the 14th century or at the very beginning of the 15th century, appears towards the end of the Middle Ages in the library of the Supersaxo family, one of the most important libraries of Valais, which today is held in the Médiathèque Valais-Sion and (this manuscript) in the State Archives of Valais in Sion. The work is remarkable in more ways than one: first, it was created in the rarely-used scroll format, a format reserved for, among others, universal chronicles, a genre to which this manuscript belongs. Second, a complex family tree, showing the descendants of Adam until the birth of Christ, runs the entire length (eight meters) of the manuscript. The columns of text of this impressive graphic document are accompanied by numerous drawings that resemble the style of Parisian works. Finally, this exemplar is not unique, since the municipal library of Reims owns a similar scroll (ms. 61), which certainly was illustrated by the same master. (rou)
